Abstract
528,320. Electric heating of metal powders. BERGHAUS, B. April 25, 1939, No. 12377. Convention date, April 30, 1938. Addition to 504,249. Drawings to Specification. [Class 39 (iii)] Sintered bodies are manufactured from metal powders by subjecting the material to an electric gas discharge in the manner described in the parent Specification, the articles of pressed powders being subjected to the gas discharge at reduced pressure, being connected as an anode or neutral for the purpose of being heated and sintered. The apparatus is similar to that described in Specification 520,589.
